To Prove Sum Of All The Angles Of Quadrilateral Is 360 Degree Youtu 1. find the fourth angle of a quadrilateral whose angles are 90°, 45° and 60°. solution: by the angle sum property we know; sum of all the interior angles of a quadrilateral = 360°. let the unknown angle be x. so, 90° 45° 60° x = 360°. 195° x = 360°. x = 360° – 195°. Hence, the sum of all the four angles of a quadrilateral is 360°. solved examples of angle sum property of a quadrilateral: 1. the angle of a quadrilateral are (3x 2)°, (x – 3), (2x 1)°, 2(2x 5)° respectively. find the value of x and the measure of each angle. solution:. Here's a fun activity to prove that the sum of all angles of a quadrilateral is 360°.hope you like it!~by mahe fatima. According to the angle sum property of a quadrilateral, the sum of all its four interior angles is 360°. this can be calculated by the formula, s = (n − 2) × 180°, where 'n' represents the number of sides in the polygon. in this case, 'n' = 4. therefore, the sum of the interior angles of a quadrilateral = s = (4 − 2) × 180° = (4 − 2.
